It is obvious that the method of mounting the knob in the lock or the method or means of connecting the roll-backs or spindles to the knob and cylinder-lock are entirely immaterial to those features which are made the subjectmatter of this invention, and whileIhave shown in the drawings a preferred form of the invention it is obvious that changes may be made in the same without departure from the spirit and scope thereof. I have not attempted to illustrate the tumbler mechanism, since those parts are well known and constitute in themselves no portion of this invention.

In the drawings I have shown a key in place, and it will be seen that the tapered entrance A facilitates the ready introduction of the same into the key-barrel.

W hat I claim is- 1. In a knob, a hollow body or grip portion, a threaded neck projecting therefrom, an aperture in. the outer and inner ends of said grip portion one of said apertures being enlarged at the side, a pin-tumbler lock carried within said body portion, a lateral projection from the body of said lock projecting into the enlargcn'ient in said aperture, a shank arranged to screw onto said threaded neck and hold said lock in place against longitudinal displacement.

2. In a device of the character described, a hollow body or grip portion, an opening in the outer face thereof and an opening in the inner face thereof opposite the first opening, a removable knob-shank, means for securing the same to the said knob-body and to cover one of said openings, a cylinder-lock, the case of said cylinder-lock being supported in said body, a lateral projection from said lock-case engaging with a corresponding notch in the body to prevent rotation of said lock-case.

3. A hollow seamless knob, a passage through said knob, a pin-tumbler lock seated within said knob and in said passage, means to prevent the rotation of the pin-tumbler casing and means independent of the knob for detachably holding said lock against longitudinal displacement.

a. A hollow seamless knob, a passage through said knob, a pin-tumbler lock seated within said knob and. in said passage, means to prevent the rotation of the pin-tumbler casing and means independent of the knob for detachably holding said lock against longitudinal displacement said means being an independent knob-shank said shank having a passage therethrough in line with the inner end of said pin-tumbler lock.

5. In a device of the character described, a seamless hollow knob, an opening in the outer and inner ends of said knob, the inner opening being enlarged, a pin-tumbler lock supported in said knob in line with said openings, a portion of said pin-tumbler lock-casing entering the enlargement of the inner opening to prevent the independent rotation of the knob and lock-casing, a knob-shank, ascrewthreaded connection between the knob-shank and the knob, the said shank holding the pintumbler lock in place when said shank and knob are connected.
